Explain why watching television and walking affect metabolism differently​

Answer: A. plants

Explanation:

 Plants are producers. They make their own food, which creates energy for them to grow, reproduce and survive.

Answer:

An intermediate is a species which appears in the mechanism of a reaction, but not in the overall balanced equation. Examples: Amphibian/land vertebrate (Pederpes)- Intermediate form between primary aquatic Upper Devonian amphibians and early tetrapods. Lizard/snake (Pachyrhachis)—Intermediate form of snakes and an extinct lizard-like reptile. It was a primitive snake with limbs.

Explanation:

Answer: These are certain species that create “connecting links” or something like that, between the fossil record of life which help to show the slow process of speciatin.

[speciatin- the formation of new and distinct species in the course of evolution.]

The statement is false. While class I MHC molecules are present on the surface of almost all nucleated cells, class II MHC molecules are limited to specific immune cells.

Not all human cells have both class I and class II major histocompatibility complex (MHC) molecules on their membrane surface. The distribution of MHC molecules differs between different cell types.

Class I MHC molecules are found on the surface of almost all nucleated cells in the body. They are responsible for presenting intracellular peptides to cytotoxic T cells (CD8+ T cells). Class I MHC molecules play a crucial role in immune surveillance and defense against infected or abnormal cells.

On the other hand, class II MHC molecules are primarily expressed on antigen-presenting cells (APCs) such as macrophages, dendritic cells, and B cells. They present extracellular peptides to helper T cells (CD4+ T cells), which are involved in coordinating immune responses. Class II MHC molecules are important for activating specific immune responses against pathogens.

While class I MHC molecules are present on the surface of almost all nucleated cells, class II MHC molecules are limited to specific immune cells. Therefore, it is false to say that all human cells have both class I and class II MHC molecules on their membrane surface.

Explanation:

Natural rights are those that are independent of the laws or customs of any particular culture or government, and so are universal, fundamental and inalienable

These rights were bestowed by God and cannot ever be taken away or even ceded. These fundamental natural rights are "life, liberty, and property,"

Human laws cannot nullify them, but an individual can lose the ability to enjoy them by acting in a certain way, like by wrongfully abusing the rights of others.

Natural rights are not generally embraced, in part because of their apparent incoherence and religious connotations.

Some philosophers contend that only legal rights exist and that there are no natural rights; for example, Jeremy Bentham referred to natural rights as "simple nonsense."

2x2 Punnett squares represent crosses between monohybrid individuals and are composed of two rows and two columns. We can use a punnett square to predict the outcome of self-fertilization for the f1 hybrids of a monohybrid cross. In this case, the punnett square should be set up as a 2x2 square.

The Punnett square is a representation of crosses between different individuals, in which the probabilities of getting offspring with different genotypes and phenotypes are expressed.

During these crosses, different gamete combinations occur according to the alleles involved in a cross. Let us remember that each gamete carries an allele of one of the involved genes.

In Punnett squares, raws represent one of the parental gametes, and columns represent the other parental gametes. Gamete combinations occur when raws and columns intercross.

When talking about monohybrid crosses, we assume we are referring to a single diallelic gene coding for a single trait. Since two alleles are involved, the Punnett squares that represent this cross will be composed of two rows and two columns. It is a 2x2 Punnett square.

We can use a punnett square to predict the outcome of self-fertilization for the f1 hybrids of a monohybrid cross. In this case, the punnett square should be set up as a 2x2 square.

The number of cells of Staphylococcus aureus present into the open wound, which divides by binary fission once every 30 minutes, after 30 minutes, one hour and 12 hours will be 2, 4 and 1.7 × 10⁷ cells respectively.

Binary fission is the method of asexual reproduction. It is the process by which a cell divides to form two daughter cells.

According to the question, the cell divides into 2 once after every 30 minutes.

The number of cells can be calculated by the formula: 2ⁿ

(where n = number of times the cell will divide in the given time period)

Therefore after 30 minutes, number of cells = 2¹ = 2.

Similarly, after 60 minutes, number of cells = 2² = 4.

In 12 hours, the cell will divide 24 times,

Hence the number of cells will be = 2²⁴ = 1.7 × 10⁷ cells respectively.

The group of cells in the hypothalamus that is stimulated by food intake is known as the eating center. The correct option is A) eating.

The hypothalamus is a part of the brain that links the nervous system to the endocrine system through the pituitary gland. The hypothalamus contains various nuclei that regulate a variety of physiological and behavioral processes, including the regulation of appetite and energy expenditure.

There are two types of nuclei present in the hypothalamus; one is the hunger (feeding) center, and the other is the satiety center. Hunger refers to the desire to consume food, while satiety refers to the sensation of being full or satisfied after eating. The hunger center is responsible for stimulating food intake, while the satiety center is responsible for suppressing food intake.

The hypothalamus, which is the area of the brain that regulates eating and drinking, is stimulated when the body requires food. Hormonal changes signal the hypothalamus to increase or decrease appetite, depending on the body's needs. Eating too much or too little can lead to hormonal imbalances, resulting in obesity or anorexia.

Facilitated diffusion is an example of passive transport. Therefore, the correct statement is option A.

Facilitated diffusion is a type of passive transport where molecules move across the cell membrane from an area of higher concentration to an area of lower concentration. The movement of these molecules required the presence of transport proteins, which act as channels or carriers for the molecules.

Active transport requires energy for the movement of molecules against the concentration gradient. However, facilitated diffusion does not require any energy for the movement of molecules and depends on the natural movement of molecules down their concentration gradient.

Facilitated diffusion also allows cells to selectively transport molecules across their membranes, such as glucose being transported into cells by facilitated diffusion using transport proteins.

Therefore, facilitated diffusion is a type of passive transport as it does not require any energy for the movement of molecules in and out of the cell.

Explanation:

Photosynthesis and cellular respiration play critical roles in the carbon cycle, which is the natural process that regulates the amount of carbon dioxide in the atmosphere.

During photosynthesis, plants use energy from the sun to convert carbon dioxide into organic compounds and release oxygen as a byproduct. Conversely, during cellular respiration, living organisms, including plants, animals, and humans, consume oxygen and organic compounds and produce carbon dioxide as a waste product.

The problem of excess carbon dioxide in the atmosphere arises because human activities, such as burning fossil fuels and deforestation, have disrupted the natural balance of the carbon cycle. This disruption has led to an increase in atmospheric carbon dioxide, which is a potent greenhouse gas that traps heat and contributes to climate change.

To decrease this problem, we can use the knowledge of photosynthesis and cellular respiration to develop strategies that promote carbon sequestration. Carbon sequestration refers to the process of capturing and storing carbon dioxide in natural or artificial sinks, such as forests, soil, and oceans. By increasing the number of trees and plants, we can promote photosynthesis and remove carbon dioxide from the atmosphere.

The structure that connects bone to bone and provides stability around a joint is called a ligament.

The Ligaments are tough bands of fibrous connective tissue that are responsible for holding bones together at a joint. They provide stability by restricting excessive movement and preventing dislocation of the joint.

Ligaments are composed of collagen fibers that are strong and flexible, allowing them to withstand tension and support the joint during various movements.

They play a crucial role in maintaining joint integrity and preventing joint instability. The ligaments also contribute to proprioception, the body's awareness of joint position and movement, helping to coordinate and control joint actions.
